Nontuthuzelo Msibi not updating me

In the 1st of August I spoke to Nontuthuzelo Msibi requesting a refund on my account as I was double charged, she advised me that it'll take 14-21 business days and advised to calle back, 21 days later, no call or email from her. I sent her an email today and she never even bothered to respond back, indeed Cartrack's service will NEVER improve, this is a fact and it actually keeps getting worse each day.
